In Canada, the prevalence and incidence of HIV remain high among men who have sex with men (MSM). Moreover, epidemiological data show that a significant proportion of transmission can be attributed people who are unaware of their HIV status. To address these challenges, HIV testing has the potential to be a major prevention strategy. Indeed, the combination of testing and treatment (test & treat) is now seen to be one of the most promising strategies in terms of its potential contribution to the eradication of HIV.
